Command
mode
: VRRP protocol configuration mode
Usage Guide
: The interface monitor function is a valuable extension to backup function,
which not only enable VRRP to provide failover function on router (or L3 Ethernet switch)
fail, but also allow decreasing the priority of a router (or L3 Ethernet switch) to ensure
smooth implementation of backup function when status of that network interface is
down
.
When this command is used, if the status of an interface monitored turns from
up
to
down
, then the priority of that very router (or L3 Ethernet switch) in its Standby cluster will
decrease, lest Backup cannot changes its status due to lower priority than the Master
when the Master fails.
Example
: Configuring vrrp monitor interface to vlan 2 and decreasing amount of priority
to 10.
Switch(Config-Router-Vrrp)# circuit-failover vlan 2 10
